UFC on FOX 7 takes place at HP Pavilion in San Jose, Calif. The main card airs on FOX with a headliner between UFC lightweight champion Benson Henderson and final Strikeforce titleholder Gilbert Melendez.

Dillashaw is currently ranked No. 14 in the USA TODAY Sports/MMAjunkie.com MMA bantamweight rankings. Since a runner-up finish on “The Ultimate Fighter 14,” the former collegiate wrestler and current Team Alpha Male fighter has posted consecutive wins over Walel Watson, Vaughan Lee and Issei Tamura.

Meanwhile, Viana, a semifinalist on “TUF: Brazil,” picked up a split-decision victory over John Teixeira in his official UFC debut this past year. The Brazilian then dropped down from featherweight and followed it with a knockout win over bantamweight Reuben Duran.
